Rubio's book media blitz continues

Sen. Marco Rubio, R-Fla., met with reporters Thursday to tout his new book -- and of course got asked about everything from immigration to the pending contempt vote in the House over the Fast and Furious controversy.

The highlights from the Christian Science Monitor breakfast: *Attorney General Eric Holder should resign, Rubio said. A House committee on Wednesday voted to hold Holder in contempt over the department's refusal to turn over documents related to the Justice Department's Fast and Furious gun operation. President Barack Obama has claimed executive privilege in the matter -- his first such assertion in his presidency.

*When asked to address the questions this week over whether he'a being vetted as Mitt Romney's running mate, Rubio declined to comment. "I don't talk about process at all," Rubio said. "But I have a new book!"

*Rubio continued to decry the politicization of the immigration debate, saying that the Obama Administrations's move last week to let some young illegal immigrants stay in this country only temporarily addresses the problem. "I think he injected election-year politics into an issue that, privately, we were making progress on," Rubio said.
